Major Description
lens.query.enable.persistent.resultset = true by default. For one the queries this value was overridden to false. This query had not finished and the lens server was restarted .On server restart all sessions had a lens.query.enable.persistent.resultset turned to false.
Reason :
LensSessionImpl.createDefaultConf() is being called by QueryExecutionServiceImpl.start() on server restart.
If a persisted query has lens.query.enable.persistent.resultset.indriver=false, then on startup the default conf can get corrupted with lens.query.enable.persistent.resultset.indriver being set to false . This will affect all the queries
